This paper discusses the access to pornographic content by adolescents in virtual environments and its repercussions for their affective-sexual lives. It explores contemporary configurations of sexuality, such as affective and sexual initiation, sexual experimentation and consolidation of the construction of the self and sexual identities during this process. The theme of pornography is thought from the crossing that access to virtual environments has today in the lives of adolescents. The study of the access to virtual environments related to sexuality brings relevant contributions to the field of knowledge about adolescents and to the health field, pointing out new elements for the analysis of the constitution of these subjects. The analysis of this access is fundamental to the understanding of the changes linked to the modes of interaction of adolescents among themselves and of the changes related to sexuality, affective life and sexual life. This work is based on a systematic review that advocates primary studies on sexuality and adolescence available in various databases; retrospective interviews conducted with young people between 18 and 24 years, both sexes, from two Brazilian cities, about the retrospective trajectory of amorous and sexual initiation, which occurred during adolescence until the current moment of trajectories, which includes affective and sexual life with a focus on the theme of pornography; and analysis of data from a representative survey of Uruguayan high school students, which correlates pornography use with indicators of sexual risk and socialization. The data point to the common use of online pornography among adolescents and the impact on their affective and sexual lives. These impacts range from the search for certain sexual practices; the discourse of pornography addiction and the harm it brings; recognition of violence in online pornography. It is necessary to think about these effects of online pornography, promoting affective-sexual education for adolescents.
